The purpose of configuring hive and HBase integration is to use the HQL syntax to implement additions and deletions of hbase database, the basic principle is to use the API interface between them to communicate with each other, the communication is mainly dependent on the Hive_hbase-handler.jar tool class. Note, however, that using hive to manipulate tables in HBase simply provides convenience, as described

Opening Remarks: Hive and HBase integration function is to use their own external API interface communication, mutual communication is mainly rely on hive_hbase-handler.jar tool class (HiveStorageHandlers: there is still some interest in hive_hbase-handler.jar this stuff, free to grind.

The integration of hive and hbase is to use their own external API interface to communicate with each other, communication is mainly dependent on hive-hbase-handler.jar tools; hive-hbase-handler.jar in the hive lib package instead of in hbase Lib, hive0.6 version later; Create an hbase table when creating a

I've described two ways in which hive imports analysis results into MySQL tables, respectively: Sqoop import and Using hive, MySQL JDBC driver, now I'm going to introduce a third, and use a lot more ways--using hive custom Functions ( UDF or genericudf) inserts each record into a database table.First, using the UDF methodUsing UDF is a simple implementation, as

The parameters in hive are divided into three categories, the first system environment variable information, the environment variable information, the second is ENV environment variable information, is the current user environment variable information; The third is the hive parameter variable information, is the environment variable information defined by the Hive
